In order to clarify the leaching behavior of elements from the damaged MOX fuel during wet storage, leaching tests were carried out on sliced samples of spent MOX fuel in borated water. The characteristics of the leaching behavior of elements from MOX fuel are reported by comparing with the leaching behavior of spent UO₂ fuel and TMI-2 fuel debris samples obtained previously.
